<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>It </em><em>means </em><em>that </em><em>the </em><em>mass </em><em>of </em><em>any </em><em>element </em><em>will </em><em>be </em><em>equal </em><em>before</em><em> </em><em>and </em><em>after </em><em>the </em><em>reaction</em><em>.</em>
Answer:
i think i can answer that because the question is not defined so its hard for me to answer
